Hi all, in recent private discussion the question was raised whether the explicit representation of multisets should follow that of sets.
For sets, we have:
{a, b, c} = insert a (insert b (insert c empty))
For multisets, we currently have:
{#a, b, c#} = single a + single b + single c
But the following would also be possible:
{#a, b, c#} = insert# a (insert# b (insert# c empty#))
Is there any evidence that we should not attempt this?
Cheers,
Florian
